Mold-proof

Mold-proof coating agent
Mold-proof coating agent exhibits a strong inhibition/prevention effect against 397 types of fungus and bacteria including 57 types of molds that exist in general buildings through combination of repellent effect and blocking effect. It also exhibits superior safety, and its effect lasts for a long time as it is a nonvolatile agent.

Characteristics

1. Broad antibacterial spectrum
2. Hard to generate resistant strains
3. A nonvolatile agent with long-lasting effect
4. Superior safety

Evolving fungi
Reproductive power of fungi is strong, and they instantly reproduce with little nutrition and water. Disinfectants and inorganic antibacterial agents perform sterilization by destroying cell membranes and nuclei, therefore warning won’t be communicated and fungi will reproduce and germinate at the same spot.
By repeating sterilization and germination, resistant strains will be generated to which the same sterilizing agent won’t work anymore.

Mechanism
Repels fungi not by killing them but by signaling warning.

STEP01

Destroys only the outside membranes (mantle) of bacteria and fungi (molds) by a composite synthetic agent containing organic ingredients.

STEP02

Synthesis of protein, DNA, SH-groups, etc., of bacteria and fungi whose mantles are damaged are inhibited, and thus anti-bacterial effect is exhibited.

STEP03

Bacteria or fungi whose synthesis are inhibited send warning signals to strains of the same species, so the same species will start avoiding that spot (repelling effect). Also, as they won’t be able to obtain nutrition necessary to grow, they will die eventually.

Inhibitory effect

1. Disturbs the function by damaging only the cell membrane/wall.
2. Elution of minerals from inside the cell (nucleotides, amino acid, protein)
3. Enzyme action is inhibited by blocking synthesis of nucleic acid and protein (random reactions with protein and amino group, phenolic group, SH group, etc. of nucleic acid)
4. Denaturation and coagulation of protein.
5. Reacts with SH in the cell and SH-enzyme and electron transport system are blocked.
6. DNA reproduction is blocked.
7. Mitosis and mycelium elongation are blocked.
8. Breathing is blocked.
9. Lipid synthesis is blocked.
10. Energy transfer is blocked.

Wide antibacterial spectrum
There are as many as 57 types of molds detected from general buildings approved by the World Society of Microorganism Disaster.
Mold-proof coating agent is effective against 397 types of fungus and bacteria, including these molds.

Coat type Water Painted surfaces, resin.
Demonstrative test of mold-proof coating agent 1
Removed mold on sealant around the window frames in the bathroom using chlorine mold remover. Sprayed them with mold-proof coating agent (coat type) and monitored the effect.

Before cleaning
After 7 months
After 14 months
Test result

Mold-proof effect lasted for more than 1 year, and molds were easily eliminated and penetration of molds into the sealants was prevented.

Demonstrative test of mold-proof coating agent 2
Applied mold-proof coating agent (penetration type) to half of the sealing material. Monitored generation of molds under the hot and humid atmosphere of the bathroom.
