TRAPYLEN primers for films, foils and sheets
Ready-to-use primers for coating TPO and PE films, foils and sheets. Solvent and waterborne, chlorinated and chlorine free, with matt versions available.
Ready-to-use primers for coating TPO and PE films, foils and sheets. Solvent and waterborne, chlorinated and chlorine free, with matt versions available.
TPO and PE films take a coating only after their surface is prepared, and the TRAPYLEN case two grades are ready-to-use primers for exactly that step. They ship at application solids, run on a rotogravure station at 0.5 to 5 grams per square meter dry, and leave the film paintable. Typical downstream work is coated TPO film and sheet for interior and exterior parts, decorative foils and laminated structures.
The case splits by carrier and by chlorine. T 4121, 8000 and T 8280 are solvent grades in toluene, with 8000 built for TPO film and crosslinkable for higher heat and chemical resistance. X 9100 M is chlorine free in xylene. The three waterborne grades, 9350 W, 9352 W and 9703 W, are chlorine free dispersions, with 9703 W aimed at PE film. Matt versions with matting agents are available across the case.
Several grades run as two-component systems with a crosslinker added before application, which raises resistance against chemicals and temperature. The chlorine free TPO primers want a physically pretreated surface, corona to roughly 50 millinewtons per meter, before application.
Tramaco also makes TRAPUR polyurethane primers for PVC and TPO film. They are a separate line, and we quote them on request.

Dosage: 0.5 to 5 grams per square meter calculated on solids, applied as delivered. Blended into a base coat as an adhesion promoter, 9350 W runs at about 30 percent of the total formulation.
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 |

| 8000 | Modified CPO | 2.5% | Solution in toluene | 10% | For TPO film, crosslinkable, contains matting agents |
| T 8280 | CPO | 26% | Solution in toluene | 10% | For TPO film, high film flexibility |
| X 9100 M | APO | Chlorine free | Solution in xylene | 12% | For TPO film, contains matting agents |
| 9352 W | APO | Chlorine free | Waterborne dispersion | 12% | For TPO film |
| 9703 W | APO | Chlorine free | Waterborne dispersion | 12% | For PE film |
| 9350 W | APO | Chlorine free | Waterborne dispersion | 12% | For TPO film, also runs as an adhesion promoter in inks and paints |
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.
The core of the case. 8000, T 8280, X 9100 M and the waterborne 9350 W and 9352 W leave TPO paintable.
9703 W is the grade aimed at polyethylene film.
Primed film carries print, adhesive or a decorative coat in the following station.
The crosslinkable grades where the coated film faces chemicals or heat.
It is specified where the formulation needs ready to use at delivered solids, no dilution step, chlorine free options in solvent and in water, matt versions available with matting agents, crosslinkable grades for chemical and heat resistance, and runs on a standard rotogravure primer station.
The primers are ready to use and are applied in delivered form, typically by rotogravure with a 60 or 80 point gravure roller. Spraying, dipping and printing also work where the line allows.
Drying runs 30 seconds at 80 degrees C for the solvent grades and 60 seconds at 80 to 100 degrees C for the waterborne grades. TRAPYLEN films form at room temperature once the carrier has evaporated, so temperature and air flow set the real line speed.
The two-component options take their crosslinker before application and hold a pot life of at least 8 hours, so a shift runs on one mix. Crosslinking raises heat and chemical resistance of the coated film.
The chlorine free TPO primers want the film corona treated to a surface tension of about 50 millinewtons per meter before application. Grades containing matting agents need a stir before every use.
Protect the waterborne grades from frost.
Package sizes: Iron drums of 170 kg for the solvent grades, PE drums of 120 kg for the waterborne grades. Other packing on request..
Storage: At least 6 months in closed original packing at 15 degrees C. Protect the waterborne grades from frost.
Refer to the current safety data sheet for hazard classification and handling. The APO grades are chlorine free per Tramaco's published data.
8000 for a solvent line and 9350 W or 9352 W for a waterborne one. If the specification excludes chlorine, X 9100 M covers the solvent side and the 9000-series dispersions the water side. Send us the film and the coating that follows and we will confirm the candidate before the sample ships.
For the chlorine free TPO primers yes, to a surface tension of about 50 millinewtons per meter. The chlorinated grades are less demanding, and the honest answer for your line comes from a trial on your film.
Yes. Matt versions with matting agents are available across the case, and 8000 and X 9100 M carry matting agents as standard. Stir before every use.
PVC is not polyolefin work. Tramaco's TRAPUR polyurethane primers cover PVC film, and we quote them on request.
Yes. We send the Technical Data Sheet (TDS), Safety Data Sheet (SDS), and Information leaflet for films on request, in the manufacturer's current revision. Use Request TDS or SDS above and tell us what your qualification review needs.
