When spraying 2K car paint, primer plays a vital role, mainly used to improve adhesion and provide additional anti-corrosion protection. 2K primer is usually sprayed in one or two layers to ensure that the paint surface is sufficiently flat and uniform.

2K car paint can be either oily or watery, and the specific type depends on the composition and formulation of the paint base. Traditionally, 2K car paint usually adopts oily formula, but with the improvement of environmental awareness, water-based 2K car paint has gradually attracted attention.

2K car paint is widely used in the field of car painting due to its excellent performance. Its service life is generally between 5 and 10 years, and the specific time depends on many factors. Environmental factors, usage habits and construction quality will affect the life of 2K car paint.

2K paint requires specific environmental conditions during the drying and curing process. If the temperature is too low or too high, and the humidity is too high or too low, it will affect the curing effect of the paint and may cause the paint film to crack.

Primers suitable for 2k car paint include: epoxy primer, polyurethane primer, acid-cured primer, acrylic primer, etc. Primer is a coating specially used to form an initial coating on the surface of a substrate. Its main function is to provide good adhesion and provide a flat and smooth base surface.

● 1K car paint: The label will be marked as "1K" or "single-component paint", and no curing agent needs to be added. ● 2K car paint: The label will be marked as "2K" or "two-component paint", which needs to be mixed with curing agent in proportion.
