High‑Viscosity PVC Plastisol: Ideal Solution for Technical Textile Fabric Coating
Technical textiles used in civil engineering, construction and environmental protection projects demand robust, flexible coating materials that bond firmly to woven and non‑woven substrates. Ordinary liquid coatings often suffer from low viscosity, poor sag resistance and unstable performance on large‑volume continuous production lines. This is where high‑viscosity PVC plastisol comes into play.
PECOAT® PEPVC2515 is a purpose‑formulated high‑viscosity PVC plastisol paste built for pouring, drip‑spot (drip‑moulding) and roll‑coating processes. After thermal curing, it delivers Shore A 50 flexible PVC layers for composite technical fabrics. For manufacturers producing waterproof geotextiles and construction functional fabric layers, this plastisol balances processability, adhesion and finished‑part consistency.
What Is PEPVC2515 PVC Plastisol?
PEPVC2515 is a thick paste‑type liquid PVC plastisol optimised for textile composite substrates including PET needle‑punched non‑woven fabric and PP woven cloth. In its raw state, it appears as a thick white paste. Once exposed to heat at 150‑180 °C for 3‑5 minutes, the plastisol gels and fuses into a soft, tough elastic coating.
Unlike low‑viscosity plastisols that easily run off thick fabrics, its stable high viscosity supports three core industrial methods:
- Pouring coating
- Spotting / drip‑moulding (drip spotting)
- Roll‑coating for wide‑web fabric lines
Base colour is white, and custom colour tinting is available upon customer request.
Core Benefits for Textile Coating Manufacturers
- Stable high‑viscosity paste performance Consistent rheology makes it suitable for pouring, spotting and roll‑coating. Minimal dripping or sagging during processing, perfectly fit for large‑scale continuous industrial coating lines.
- Excellent adhesion on multi‑type technical textiles Offers strong bonding to needle‑punched non‑woven fabric, PP woven fabric and combined composite substrates. The coating stays attached even under bending and handling of finished geotextile products.
- Predictable thermal gelation and fusion Under standard curing conditions of 150‑180 °C / 3‑5 min, it provides repeatable Shore A 50 flexible hardness batch after batch, reducing defective rates for mass production.
- Flexible colour options Supplied as standard white paste; custom colour matching can be arranged for project‑specific fabric layer requirements.
- Qualified for industrial project supplies Compliant with REACH and RoHS requirements, supporting documentation such as TDS and SDS can be provided for customer project audits. Free samples are available for performance testing (customer covers air freight cost).
