How to use MEIBOSS paint anti-mold agent?

2021-10-25   Pageview:229

MEIBOSS anti-mildew agent has been widely used in the construction of decorative coatings, emulsion paints, water-based ink, color paste and other anti-mildew anti-bacterial treatment. MEIBOSS anti-mildew agent and most of the water-soluble coatings have good compatibility. When using, only need to add 1% to 2% in the coating (100 kg of paint plus 1 to 2 kg of anti-mildew agent) of MEIBOSS, the paint that has outstanding anti-mildew function of killing bacteria. And it meets the requirements of GB 18582-2001 (indoor environmental protection decoration materials in the interior wall coating quantification of harmful substances), does not contain formaldehyde, and does not contain formaldehyde release material.

 

 

 

 

 

 

 

 

 

 

 

 

The polymerization initiation activity of iron aromatics on epoxy and other monomers is lower than that of triarylsulfonium salt. In fact, after the iron arene/epoxy formula is irradiated with light, the cationic polymerization often fails to start. At this time, only a curing latent image is formed. The iron arene ligand replacement occurs in the area exposed to the light. Ferrocene Lewis acid combination, the new complex can not effectively open the epoxy structure to initiate polymerization, generally after the end of the light, the coating is properly heated to complete the curing and crosslinking (43. According to the reaction activity of the monomer, the post-heated The temperature and time may be different [44J, post-heating is to open the epoxy structure of the photoreaction product monomer-monoferrocene complex, so that polymerization occurs. This post-heating process (or curing lag process) looks like a light-curing technology However, it can also be found suitable for its application (45). For example, when bonding opaque materials, an epoxy formula with iron aromatic hydrocarbon as initiator can be applied to the bonding surface and exposed to light to form a resin-containing compound. The latent curing adhesive layer of the iron Lewis acid complex does not cure immediately. The adhesive layer of the bonded material is attached to the adhesive layer and heated for a few minutes to form a good quality adhesive layer. synthetic paraffin chemical formula,  This formula does not contain volatile components It is especially suitable for bonding non-permeable materials.

Photoinitiator for water-based photocurable coatings
With the continuous strengthening of environmental protection, chemical products are also developing in an environmentally friendly direction. It is under this background that water-based light-curing coatings have received attention and development, in order to meet the good dispersion and solubility of photoinitiators in water-based systems. , The research and development of water-based photoinitiator (WSP) has also been greatly developed. According to the chemical structure, the current water-soluble photoinitiators can be divided into aromatic ketones, condensed ring aromatic hydrocarbons, polysilanes, aroyl phosphonates, azos and metal organic complexes, among which aromatic ketones The most abundant category can be divided into thioxanthone derivatives, benzophenone derivatives, benz il derivatives and alkyl aryl ketone derivatives.
