Anti-mold AgentsInorganic/Organic hybrid Anti-mold Agent CAVINON®

CAVINON® is an organic/inorganic hybrid anti-mold of which anti-mold component is intercalated in an inorganic layered compound. CAVINON® has features such as heat resistance, water resistance, and sustainability which are difficult to obtain with conventional organic anti-mold agents. It can be used in a variety of applications where durability is required.

Features

Able to be molded into resin due to its high heat resistance.
Designed to release active ingredient gradually and keeps long lasting effect.
Resistant to water and chemical.
Effective against wide range of molds.

Specification

Grade and characteristics

Grade	Characteristic	Appearance	Average particle size	Heat resistance
CAVINON_®800	Standard	White ⁓ pale yellow	5 μm	Approx. 250℃
CAVINON_®900	Anti-mold + Anti-bacteria	White	4 μm	Approx. 270℃
CAVINON_®740HV	For plastic	White ⁓ pale yellow	5 μm	Approx. 250℃
CAVINON_®940	For sealant, paint	Pale yellow	4 μm	Approx. 230℃

Mechanism

CAVINON® exhibits its anti-mold effect by gradually releasing an active ingredient, causing functional inhibition inside mold cells and eliminating the regeneration of fungal cells.

Anti-mold effect

CAVINON® shows anti-mold effect against a wide range of microorganisms.

Product performance

Example of application in polyethylene resin

The anti-mold effect lasts for a long time since CAVINON® is difficult to bleed out. (Halo method, Cultivation 7 days)

	Initial	After 90 days
0.5% of CAVINON_®800
0.5% of Triazole based anti-mold agent
0.5% of Haloalkylthio based anti-mold agent

Example of application in sealant

The silicone sealant containing CAVINON® exhibits an excellent anti-mold effect even after being immersed in running water for 200 hours. (Method B of JIS Z 2911 for plastics)

	Initial	After 200 h in running water
