TerasKelebihan
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.

ApplicationProcess
Penyediaan permukaan
Amplas substrat ke Sa2.5 / St2 dan buang minyak serta habuk. Amplas dempul dengan kertas P240-P320 sehingga licin.
Pencampuran
Main agent: curing agent = 4:1, mix evenly. Add 10-20% thinner to adjust viscosity based on the application method. Filter through a 200-mesh screen before use.
Aplikasi semburan
HVLP spray gun / 2.0-2.5 bar / 15-20 cm. Apply 2-3 coats, with 5-10 minutes of flash-off between each coat. Total film thickness: 60-80 μm.
Keringkan & amplas
Dries hard at 60°C for 30 minutes or at 25°C for 2-4 hours. Wet sand with P400-P600 sandpaper until the surface is smooth, then clean and remove dust.
Salut antara / Salut akhir
Selepas amplas dan bersih primer, terus sapukan primer surfacer atau cat asas. Pastikan permukaan kering, bersih dan bebas kontaminasi.
