TRAPUR is the polyurethane half of Tramaco's primer range, covering the substrates the chlorinated polyolefin TRAPYLEN grades are not built for. The three current grades are ready-to-use primers that run on a rotogravure station at 0.5 to 2 grams per square meter dry, and every one is chlorine free by chemistry.
TRAPUR 113 is the solvent workhorse, an aromatic polyurethane in MEK and ethyl acetate with outstanding adhesion on PVC, PES, PS, ABS and rubber. It also pretreats polyolefin foils after a corona step. TRAPUR 115 X is the TPO-foil specialist; a foil primed with it takes a topcoat and then embosses easily, which is what decorative interior film work needs. TRAPUR 209 W is the waterborne grade, an aliphatic polyurethane dispersion that dries to a glossy, tack-free film on PP, PES and rubber.
All three run as one-component primers or as two-component systems with a polyisocyanate crosslinker, which raises heat stability, chemical resistance and, on 209 W, resistance against plasticizers. Pot life with crosslinker is at least 8 hours, so a shift runs on one mix.
A coated-substrate line can pair TRAPUR surface preparation with a topcoat system from ROWA Lack, Tramaco's sister company in the ROWA Group, and take both from us in one supplier relationship. These are made-to-order products from the German plant, so plan a first order against a trial.
| Property | Typical value |
|---|---|
| Chemistry | Aromatic polyurethane in solvent, aliphatic polyurethane dispersion in water |
| Chlorine content | Zero, the whole line is chlorine free |
| Forms | Ready-to-use solutions in MEK and ethyl acetate or in mixed solvents, and a waterborne dispersion |
| Solids content | 9.6 to 10.4 percent as delivered, with 113 also made at 30 percent |
| Application rate | 0.5 to 2 g per square meter, calculated on solids |
| Crosslinker dosage | 2 to 5 percent polyisocyanate by grade, pot life at least 8 hours |
| Matt versions | 115 X and 209 W are available with matting agents |
| Storage stability | At least 6 to 12 months in closed packing at 15 degrees C, by grade |
Dosage: 0.5 to 1.5 grams per square meter on solids for the solvent grades and 0.5 to 2.0 for 209 W, applied as delivered. Crosslinker dosage is 5 percent on 113, 2 percent on 115 X and 4 percent on 209 W.
Typical values from the manufacturer's technical data sheet. They describe the product, they are not a specification. We will send the current TDS and the batch documentation your qualification needs.
Tell us the binder system, the property you are targeting, and the volume you expect. We will confirm the grade, send the documentation, and get a sample of the candidate grade to you.
| Grade | Chemistry | Chlorine content | Form and carrier | Solids or Mw | What it is for |
|---|---|---|---|---|---|
| 113 | Aromatic PUR | Chlorine free | Solution in MEK and ethyl acetate | 10.4% | PVC, PES, PS, ABS and rubber, plus corona-treated polyolefin foils |
| 115 X | Aromatic PUR | Chlorine free | Solution in mixed solvents | 10.4% | PP, TPO and TPE foils that will be topcoated and embossed |
| 209 W | Aliphatic PUR dispersion | Chlorine free | Waterborne dispersion | 9.6% | PP, PES and rubber, glossy tack-free film, waterborne lines |
Values are the manufacturer's published typical figures. Ask for the current technical data sheet on any grade and we will send it with the matching safety data sheet.
113 on PVC film ahead of print, lamination or a topcoat.
115 X leaves the foil paintable and embossable, the sequence decorative automotive and furniture films run.
113 in solvent or 209 W in water, ahead of paint or adhesive.
209 W keeps the primer station water-based and dries tack free.
It is specified where the formulation needs covers the substrates outside TRAPYLEN's polyolefin lane, chlorine free by chemistry, in solvent and in water, one-component or crosslinked two-component operation from the same drum, primed foils emboss cleanly after topcoating on 115 X, and runs on a standard rotogravure primer station.
The primers are ready to use and are applied in delivered form, typically by rotogravure. 209 W also runs by roller or spray gun. Recommendations depend on the application process and are optimized per substrate in the trial.
Drying runs 30 seconds at 80 to 100 degrees C for the solvent grades and 60 seconds at 80 to 100 degrees C for the waterborne grade.
For heat stability and chemical resistance, crosslink with polyisocyanates: MDI types on 113, HDI types on 115 X, and a water-dispersible polyisocyanate on 209 W. The crosslinker goes in before application and the mix holds a pot life of at least 8 hours.
Coating polyolefin foils with 113 or 115 X wants a corona treatment to a surface tension of about 50 millinewtons per meter first.
Protect 209 W from frost. Grades with matting agents need a stir before every use.
Package sizes: Iron drums of 170 kg for the solvent grades, PE drums of 120 kg for 209 W. Other packing on request..
Storage: At least 12 months on 113 and 209 W and at least 6 months on 115 X, in closed original packing at 15 degrees C. Keep 209 W from frost.
Refer to the current safety data sheet for hazard classification and handling. The line is chlorine free by chemistry.
When the substrate is not a polyolefin. PVC, PES, PS, ABS and rubber are polyurethane territory, and 113 or 209 W covers them. On PP, TPO and TPE foils both chemistries can work; 115 X is the choice when the primed foil has to emboss after topcoating. Send us the substrate and the following coat and we will confirm the candidate.
No. All three grades work as one-component primers. The crosslinker is added when the coated part faces heat, chemicals or plasticizer migration, at 2 to 5 percent depending on grade, and the mix still holds a pot life of at least 8 hours.
Yes, 209 W, an aliphatic polyurethane dispersion at 9.6 percent solids that dries to a glossy, tack-free film. It crosslinks with a water-dispersible polyisocyanate when the job needs the two-component properties.
Yes. Tramaco and ROWA Lack are sister companies in the ROWA Group, and we distribute both. Tell us the build of the material and we will line up the TRAPUR primer and the ROWA topcoat as one package.
Yes. We send the Technical Data Sheet (TDS), Safety Data Sheet (SDS), and Information leaflet for painting TPO foils on request, in the manufacturer's current revision. Use Request TDS or SDS above and tell us what your qualification review needs.
