# About Karmind Hebei Karmind Plastic & Rubber Products Co., Ltd. — a manufacturer of one-component polyurethane sealants and adhesives in Wei County, Hebei, supplying automotive, construction and industrial customers at home and abroad. The plant in Wei County, Hebei. Product display and brand materials. Bonding, sealing and protection. ## What we make The range runs across five chemistries: polyurethane windscreen and body sealants, construction joint sealants, silyl-terminated polymer (STP) sealant, PUR wood adhesive, and the activators and primers that decide whether any of them bond. The company's own account of the product line is that the second- and third-generation sealants bond a range of substrates without a primer coat, contain no isocyanate and no solvent, and are formulated to avoid the additive deactivation that shortens the life of earlier one-component systems. Those are the claims we can repeat. The number on a data sheet is the number to test. ## What we do not make We make one-component moisture-curing polyurethane sealants, STP, PUR for timber, and the activators and primers that go with them. We do not make silicone sealants, structural epoxy or crash-rated panel adhesives, and we do not relabel another plant's product under our name. Where a job needs one of those, the honest answer is that it is not our family. ## One plant, one set of records All ten grades come from Wei County. That is deliberate: one site means one batch-record system, one traceability chain and one answer when a certificate is queried. It also means we cannot offer a second origin or a co-manufactured grade at short notice, and we say so before a quote rather than after an order. ## How we work with buyers - Distributors — pallet mixes across models, private label, consistent colour across batches. - Body shops and glass installers — the fast-positioning grades, in cartridges sized to the bay. - Construction suppliers — high-elongation joint sealants in sausage and barrel for site work. - Industrial OEMs — STP and PUR systems for metal, plastic, glass and timber assemblies. ## Markets Products are exported across Europe, the Americas, Africa, Asia and Oceania. In 2026 the company exhibited at the 140th Canton Fair and at YAMPFAIR; both are a reasonable place to put a face to the email address before placing a first order. ## Who writes this site The technical pages are written by the Tech Department and reviewed by Wang from three sources: the printed catalogue and its test methods, the batch records held at the Wei County plant, and the standards that govern the product family (GB/T 528, GB/T 7124, GB/T 13477, HG/T 4363, and EN 15651 where a European project requires it). No page here is a guest post, a paid placement or a rewritten supplier brochure. Where a figure is a catalogue typical value rather than a measurement of the lot you will receive, the page says so. Where a claim depends on a certificate we have not been given a copy of, we do not print the claim. The rules we hold ourselves to — and the limits of a manufacturer publishing its own data — are set out on the [methodology page](https://karmindadhesive.com/methodology/). ## How to verify us before an order Due diligence should take an afternoon, not a leap of faith. These five documents should name the same legal entity and the same address: - Business licence (company name, registration number, registered address). - ISO 9001 and ISO 14001 certificates, with scope and validity dates. - A batch record for the lot being shipped: batch number, method, result, specification range, operator. - The test report behind any figure you intend to write into a contract. - An SDS in the language of the destination country, with the CLP classification where the EU applies. Ask for them together. A supplier who can produce one document quickly and the rest never is telling you something about the filing system, and possibly about the certificate. We would rather be asked than trusted. ## The legal entity | English name | Hebei Karmind Plastic & Rubber Products Co., Ltd. | | Address | Wangshigong Industrial Zone, Wei County, Hebei Province, China | | Telephone | +400-088-0319 | | Email | martin@karmindadhesive.com | [Doing due diligence?
