Car shock absorber black electrophoresis paint by Low temperature curing
Product Introduction :
OHT-825/OHT-825 Ultra Low temperature Black Cationic Epoxy Electrocoat, is HLS Paint (Shanghai) Co., Ltd. the ninth generation of independent research and development of electrophoretic coating. The lead, cadmium, chromium, mercury and other heavy metals, two-component aqueous dispersion resin. At the same time, inherited the characteristics of several generations of product quality, OHT-825 on galvanized steel sheet has good adaptability, almost at the bottom of all the metal material coating, such as: cold rolled steel, galvanized steel, aluminum, stainless steel plate, rubber parts, zinc and aluminum alloy plate, such as applicable.
This product features shown below:
High penetration and good uniformity of internal and external.
Excellent leveling and coating, coating, coating binding force and supporting good
Particularly suitable for high temperature baking of the workpiece, in particular, rubber and metal binding parts and zinc aluminum alloy material.
Main ingredients:
Neutralizing agent: organic acid
Solvent: alcohol ether

Storage, packaging and transportation
This product is a water-borne industrial coatings, non-hazardous,
non-inflammable and explosive products; transportation to prevent
direct sunlight, avoid freezing (>5℃ ); Packaging for 50/60/200L
Plastic barrel; in the transport and storage of drums should be
maintained clean, avoid charging the dirt brought in on drums
during filling tank, again checked and confirmed that the quality
of products, including paste resin, emulsions and additives should
be indoor storage, good ventilation, dry, protect against freezing
and overheating, the storage temperature should be controlled at
5～35℃, products from the date of production, over shelf,
experimentation is required to determine whether can continue to
use.
