TWO COMPONENT POLYURETHANE AUTOMOTIVE FINISHES:
General
Description:
Khosh paint No.21, is a Polyurethane paint based on acrylic and polyurethane
resin with high gloss and stability.
It is resistant against water, abrasion and impact and splashes of petrol,
mineral and animal oils, the product is durable in severe atmospheric condition
near the sea and or industrial areas.
The paint surface easily will be cleaned from dust and other contaminations
when cured completely.
Field
Of application:
This paint is used as a decorative and protective finishing coat on various
substrates like steel, aluminium, fiber glass, reinforced polyester.
The minimum temperature required to harden is-10C.

Application
Condition:
The surface must be completely clean and dry at the time of application, and
its temperature must be above the dew point to avoid condensation. Minimum
temperature for curing is - 10 C. At the freezing point and below, be aware
of the risk of the surface which hinder the adhesion. Light rain, high humidity
and/ or condensation during application and the following 16 hours (20 C and
RH 60-85%) may adversely affect the film formation. In confined spaces provide
adequate ventilation during application and drying.
Thinning:
Thinner AB-128 is percomended as appropriate for application at temperature
up to application temperature thinner AB-129 is recommended.
