Adhesive + panel · Made in the USA
Cattie codes, PurLam brand. Moisture-cure reactive hot melt for the jobs that fail EVA — and liquid PU, PUD, and 2K where the line needs them. We specify and sell with Cattie Adhesives. Eco-Pur reacts in Romeoville. The sandwich panels next door are hot-melt PUR only — no liquid in the laminate.
Family A · sold as PurLam
Moisture-cure reactive hot melt. Applied molten, then cross-links with moisture into a thermoset. Eco-Pur lists these uses (no Eco-Pur SKUs except 12-3000):
Family B · not used in PurLam panels
Sold as adhesive. Eco-Pur lists tested uses. The Romeoville laminator does not put liquid PUR in sandwich panels — hot-melt composites only.
Named codes from cattieadhesives.com. Sold as PurLam. Where viscosity or apply-temp is blank, Cattie has not published it — we will not invent it. SDS/TDS on request.
| Grade | Open time | Viscosity | What it is for |
|---|---|---|---|
| 8600 | 4 min | 4,000 cps @ 250°F · run 235–275°F | Fast tack. Cabinets, steel, wood, EPS, cores. Extrusion or roll coater. 10 hr cure. |
| 8463 | 3–4 min | 9,000 cps @ 250°F | Very fast tack, high green strength. RV panels / RV construction. 8 hr cure. |
| 8493 | 45 min+ | 9,000 cps @ 250°F | Long open. EPS foam; flexible bonds to steel, wood, foams. 2–4 hr cure. |
| 8927 | 7 min | Not published | Composite panel lamination. Honeycomb, EPS, steel, wood, laminate. Roller. Low initial melt point. |
| 8940 / 8940M | 9 min | Not published | Same substrates as 8927. Cattie RV page uses both 8940 and 8940M — we list both, we do not invent what M means. |
| 8937 | 2–3 min | Not published | Carpet, felt, honeycomb, steel, ABS, PVC. Automotive assemblies. Roller. Low initial melt point. |
Page-level Cattie PUR claims (not SKU-specific): high green strength options; about −40°F to +300°F after cure; 50–80% of final strength in 3–6 hours; full reactive cure typically 24–36 hours; 100% solids. Packs: cartridges, foil slugs, pails, drums. Bonds wood, plastics, foam, metals, fiberglass, nylon, rubber, coated papers. SIP / door / garage door / RV walls. Pigmented and prepolymer options. Match by TDS/SDS.
Partner-plant grade · Eco-Pur, supplied through PurLam / Cattie
Hot-melt polyurethane for general assembly and hard-to-bond lamination. Public TDS (Titan / Eco-Pur, Jan 2021): excellent adhesion to PVC, ABS, PE, and PP. Swirl spray, slot nozzle, roller. Extra cross-link density for heat resistance. We skip 12-3006 — the Titan listing is messy and contradictory.
Packs (TDS): 55-gal drums (lined and unlined); 5-gal pails with and without foil liner; 2 kg slugs with foil pouch (5 in. dia.); 300 ml aluminum cartridges.
This is the only Eco-Pur adhesive grade with a public TDS. Eco-Pur’s own downloads page still says “files coming soon.” PE/PP adhesion is a 12-3000 TDS claim, not a Cattie-grade claim.
Sold as adhesive. Not used in PurLam sandwich panels — the plant constraint is hot-melt PUR only, no resin or liquid in the laminate.
Cattie’s general-purpose liquid PUR (“our version of Gorilla Glue”). Carpet, wood, foam, metal, most plastics. Permanent rigid bond. Not for vinyl (PVC), PP, PE, or polyolefins. Not tacky when first applied — clamp during initial cure. Family copy: assembly time 20–30 minutes; apply above 50°F.
Lamination of panel products. EPS foam, honeycomb, steel, wood, laminate. Roller applicator. Cattie notes year-round processing is possible. Still a liquid — not the chemistry in the Romeoville sandwich stack.
Water-borne polyurethane dispersions for vacuum-forming vinyl and PVC foils to particle board (kitchen doors, furniture, 3D laminating). Not used in PurLam sandwich panels.
Workhorse membrane-press grade. Vinyl/PVC foils to particle board. Wide operating window. Increased bond, heat, and water resistance with the isocyanate hardener.
Same process, specified for high-gloss vinyl/PVC foils. Heat and water resistance.
Membrane pressing / vacuum forming vinyl/PVC foils to particle board. Doors, cabinets, 3D. No hardener required.
7-560 — isocyanate crosslinker; water, heat, bond. 7-1001 — aliphatic PU crosslinker at 5% mix; hard-to-bond PS foam, cedar, plastics; pot life > 8 hr; non-yellowing.
Not a panel-laminating adhesive. Named because Cattie already publishes them and a PurLam buyer may ask.
Two-component polyurethane for floor-covering materials on smooth, solid surfaces. Mix A+B; cures to a tough, flexible film.
Two-part, solvent-free polyurethane for installing wall panels on clean, dry, sound walls. Non-absorbent surfaces, and absorbent surfaces in severe-use / wet / temperature-swing areas.
Not an adhesive. Cleaning compound to purge moisture-cure PUR from hot-melt applicators so cured melt does not clog machines and tips. Apply 250–350°F. 7,000 cps at 350°F.
Match by TDS, SDS, or the grade you already run. Pigmented reactive hot melts and prepolymer options. Eco-Pur reactors, batches 10 lb to 10,000 lb. PurLam sells it. Use the quote form — choose PUR adhesive (HMPUR), liquid PU, or toll batch.
A 100% solids, moisture-curing polyurethane. You apply it hot. It sets like a hot melt, then cross-links with ambient moisture into a thermoset. That cross-link is the heat, cold, and moisture resistance. Liquid PU is the room-temperature cousin: not tacky when first applied, so parts need clamp or press during initial cure.
Cattie HMPUR: 8600, 8463, 8493, 8927, 8940/8940M, 8937. Partner-plant Eco-Pur HMPUR 12-3000. Liquid: 8730, 8932. PUD: 7-859, 7-866, 7-883WH plus hardeners 7-560 and 7-1001. 2K: 7-3029, 7-3040. Purge: PUR-Purge-1000. Nothing else is invented on this site.
No MOQ on panels. Adhesive toll starts at 10 lb. The panel plant uses hot-melt PUR only — no liquid in the laminate. Ask for adhesive, panel, or both on one quote.
Yes. Cattie formulates, specifies, and sells from Quakertown, PA. Eco-Pur reacts and laminates in Romeoville, IL. Custom formulate when the catalog grade is wrong.
Cattie HMPUR grades: generally no, unless corona-treated. Eco-Pur 12-3000 TDS claims excellent adhesion to PE and PP. Those are different source documents. We do not merge them, and we qualify on your substrates.
