Sorotan produk

TerasAdvantages

Mentakrif semula standard kualiti pengecatan semula automotif

Rintangan kakisan unggul

The epoxy polyamide curing system forms a dense coating that effectively blocks the penetration of water, oxygen, and corrosive ions. It withstands over 500 hours of salt spray testing without blistering or corrosion, providing reliable long-term anti-corrosion protection for metal substrates.

Serasi dengan pelbagai substrat

It exhibits excellent adhesion to a variety of commonly used automotive substrates, including cold-rolled steel, galvanized steel, aluminum alloy, and stainless steel. There is no need to frequently switch primer products for different substrates, simplifying procurement and inventory management.

Kering cepat dan cekap

Baking at 60°C for 30 minutes allows for immediate sanding, while at room temperature (25°C), sanding can be done within 2-4 hours. The pot life extends up to 4 hours, eliminating the need for frequent mixing during large panel spraying, significantly improving construction efficiency.

Keupayaan pengisian dan pengedapan cemerlang

High-solid formulation (55%+), with excellent filling and covering ability for sanding marks and minor defects. Effectively seals the pores of the putty layer, preventing the topcoat from being absorbed and causing loss of gloss.

Keserasian tinggi

Pelekatan antara lapisan yang cemerlang pada dempul, primer surfacer, cat asas dan jas klar. Sesuai dengan sistem PPG, BASF, Axalta.
