Have many furniture manufacturer to reflect the purchase of water-borne wood coatings, batch effect difference is too big, how to also could not spraying the effect of the previous batch.
The hardness of paint is not enough, or poor plumpness.
Serious and even finish do one touch off paint, what reason is this?
1, the issue of water paint hardness
film hardness is not enough, one is the product scratch resistant components is not enough, such as wear-resistant resin content does not reach the designated position; Second, curing agent don't match, not according to the standard of form a complete set! This kind of phenomenon furniture factory are common. Some factories in order to save cost, use is not really scratch resistant curing agent, was not up to scratch resistant effect.
prepared waterborne paint can dig down? In general, such a situation is rare. Some, such as red oak, beech hardwood furniture factory used for the substrate, completes the primer on a long time to finish, when used in paint only blow down ash, immediately do paint. This is a bad phenomenon.
primers and paint painting can not be apart too long time, it is recommended to remove surface dust, with fine sand paper burnish, do it again thin primer, and then do normal paint, it can effectively avoid the paint off.
2, the question of water-based paint plumpness
want to remind you the construction personnel, curing agent can not mix. Many people put the light curing agent and the mixture of dumb light curing agent, which can lead to actual spray gloss and good furniture there are differences between the plumpness, paint must be in accordance with the ratio of identity, don't change it.
the ratio of curing agent added problems to cause a decline in solid content, viscosity is thinning, and spraying was obvious uneven, resulting in a spray gun to go too fast, directly affect the paint film plumpness.
