# Declarations and compliance Last updated: 2026-11-10 This page states what we can document for our products, and — just as usefully — what we do not claim. A declaration that cannot be traced to a certificate, a test report or a batch record is marketing, and buyers eventually discover the difference. We would rather lose a point in a comparison table than win it with a document we cannot produce. ## Management systems The company operates a quality management system and an environmental management system, and holds certification to ISO 9001 and ISO 14001. Certificates are supplied on request so the legal entity, the scope and the validity dates can be checked against the issuing body. We do not publish certificate numbers on this website, because a number without the certificate beside it proves nothing and can be copied by anyone. ## Product testing Catalogue values are measured by the methods named on each model page: | Property | Method | | Tensile strength, elongation at break | GB/T 528 | | Tensile shear strength | GB/T 7124 | | Shore A hardness | GB/T 531.1 | | Skin time, sag, extrusion rate | GB/T 13477 series | | Volatile content | GB/T 2793 | | Cure rate | HG/T 4363 | These are test methods, not certifications. "Tested to GB/T 528" means the tensile figure was obtained that way; it does not mean a third party approved the product. ## Typical values, batch records and product consistency The values printed on a model page are catalogue typical values measured by the method shown. They describe the product design, not a guarantee for every production lot. The batch certificate of analysis names the batch number, the measured result, the specification limit and the test method; that document — not the website — is the evidence for the material you receive. To confirm that a delivery matches the published data, match the carton or drum batch number to the COA and to the retained sample. If the batch number is missing, the COA belongs to another lot, or a measured result is outside the model-page limit, quarantine the material and request a deviation or a replacement before use. We do not claim that a website page can verify a physical batch without that batch record. ## Windscreen safety and drive-away statements We do not publish a universal “safe drive-away” guarantee. For a bonded windscreen, the vehicle manufacturer’s repair procedure and its stated temperature, bead geometry and retention test govern. A catalogue skin time or cure rate is a material property measured under stated conditions; it is not the vehicle-specific drive-away time. Cold glass, dry air, a thick bead or an expired cartridge can slow the cure without changing the label on the cartridge. The workshop should record glass temperature, preparation and the procedure used, and confirm the bond on the actual glass/frit where the vehicle maker requires it. A two-hour claim at 23 °C must not be repeated as a winter or all-vehicle promise. ## EU Construction Products Regulation and EN 15651 Sealants for non-structural use in buildings fall under the harmonised standard EN 15651, and CE marking under Regulation (EU) No 305/2011 requires testing to that standard plus factory production control. Our construction grades are routinely tested to the GB/T methods above. We do not claim CE marking to EN 15651 by default, and we will not print a CE mark on a carton unless the test report and the declaration of performance exist for that product. If your project requires EN 15651, say so in the enquiry. We will tell you whether the report exists for the model in question — and if it does not, we will say so rather than supply a document from a different product. ## REACH and SVHC REACH applies to substances and mixtures placed on the EU market. A sealant is a mixture, so there is no such thing as a "REACH certificate" for it; what exists is a safety data sheet, a classification, and — where a substance on the ECHA Candidate List is present above 0.1% by weight — a declaration to that effect. We provide an SVHC declaration per product and per batch on request, dated against the Candidate List in force at the time of shipment. If you need it for customs or for a customer's questionnaire, ask with the model and the destination and we will issue it with the documents. ## Safety data sheets and labelling An SDS is available for every model, in English and, where the destination requires it, in the local language. Cartons are labelled with the product name, model, batch number, production date, net content and the hazard statements that apply to that formulation. Classification varies between products — a solvent-free one-component PU and a solvent-borne primer are not in the same category — so the label on the carton, not a generic statement on this page, is the authoritative one. ## Origin and customs Goods are manufactured at Wangshigong Industrial Zone, Wei County, Hebei Province, China. The certificate of origin is issued by the competent authority for each shipment. The HS classification is confirmed per shipment with the forwarder, because the correct heading depends on the product form and on the importing country's tariff schedule; we do not publish a single code that would be wrong for half the range. ## Shelf life and storage One-component PU sealants carry a shelf life of 9–12 months when stored unopened below 25 °C; activators and primers carry six months. Heat shortens both — every 10 °C above 25 °C roughly halves the remaining life — so a container that crossed the tropics has spent part of its allowance. The production date on the carton, not the shipment date, starts the clock. ## Packaging and waste Cartridges are polypropylene with an aluminium or plastic piston; sausages are a laminated film; barrels are steel or HDPE depending on the model. Empty packaging should be handled under the waste rules of the destination country. Cured PU sealant is an inert solid; uncured residue must not be discharged to drains. ## What we do not claim - We do not claim CE marking to EN 15651 unless the report exists for that model. - We do not claim a "REACH certificate" — no such document exists for a mixture. - We do not publish certificate numbers that cannot be checked with the issuing body. - We do not claim approvals from vehicle manufacturers unless an approval letter is provided. - We do not state a service life in years; joint design, movement and exposure decide it. ## Requesting documents Send the model, the batch number if you have it, the destination country and the document you need to [martin@karmindadhesive.com](mailto:martin@karmindadhesive.com). Typical requests — SDS, batch test record, SVHC declaration, certificate of origin — are answered within two working days; a document we do not hold gets an honest "we do not have it" rather than a template.
