Common knowledge of coating: solution to wrinkle and undercut of epoxy floor coating

Core tip: the wrinkle of epoxy floor paint film is mostly caused by fast drying of paint Due to the high temperature of construction environment, large painting distance (spraying) and fast volatilization of diluent, the floor paint film is not even, which makes the paint film crinkle and orange peel In order to speed up the drying of the coating, the addition of too much drier will also cause the wrinkle of the epoxy floor coating Avoiding construction under high temperature, or strengthening ventilation, reducing construction environment temperature, adjusting painting distance, properly adding slow drying solvent and reducing the amount of drier are the methods to avoid and overcome the wrinkle of floor paint film The primer surface is not completely dry and hard, or the content of curing agent is insufficient, the floor Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Paint Home News: the wrinkle of epoxy floor paint film is mostly caused by fast drying of paint Due to the high temperature of construction environment, large painting distance (spraying) and fast volatilization of diluent, the floor paint film is not even, which makes the paint film crinkle and orange peel In order to speed up the drying of the coating, the addition of too much drier will also cause the wrinkle of the epoxy floor coating Avoiding construction under high temperature, or strengthening ventilation, reducing construction environment temperature, adjusting painting distance, properly adding slow drying solvent and reducing the amount of drier are the methods to avoid and overcome the wrinkle of floor paint film If the primer surface is not completely dry and hard, or the content of curing agent is insufficient, and the cross-linking of the floor paint film is not sufficient, the top coat or more coats will be applied, namely, the phenomenon of wrinkle and undercut will occur When nitrocellulose paint or water-based paint with high polymer content is used as primer, due to the low content of PVC, it will also cause undercut of top coat For example, a large number of slow drying ketones and other strong solvents are used in the top coat, which is also easy to cause undercut of epoxy floor paint To prevent undercutting, the mixing ratio of base material and curing agent shall be strictly controlled to ensure that the epoxy floor paint film is fully crosslinked The time of repainting should also be strictly controlled After the primer is crosslinked and dried, the top coat can be repainted It is necessary to increase the volume ratio of pigment in the primer, and choose sheet filler to strengthen the compactness of the primer, so as to prevent the floor paint from swelling and undercutting due to the excessive penetration of the finish solvent Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
