Enhancing Surface Durability with Bento-01: A Natural Additive for Water and UV Resistance

Bento-01 improves the resistance of painted surfaces to water and vapour at least in three times during long exposure to moisture. For example, in one day after painting the oil to the surface, the contact angle of the drop on the layer with Bento-01 additive and the control sample was approximately the same. However, after 5 hours, the control sample lost its water-repellent properties, while the contact angle of the drop on the surface with Bento-01 additive decreased by only 10% with maintaining good waterproofing.

In the case of testing samples after painting in month later, this trend persisted. Control sample lost its water-repellent properties after 48 hours, while the coated by oil included Bento-01sample with Bento-01 did not change its hydrophobic properties.

Testing the effect of ultraviolet radiation on surfaces was performed by shielded and unshielded areas on the painted areas with and without Bento-01 additive. It was found that after 30 calendar days in the control samples shielded and unshielded areas appearence was different while in samples with Bento-01 additive appearance do not change.

Natural additive Bento-01 based on linseed oil and natural bentonite clay additives with dispersion of 16-60 nm. Bentonite forms a gel that does not affect the appearance of the coatings.

Nano bentonite gel in linseed oil is a ready-to-use additive to increase the UV and moisture resistance of paint coatings.

Due to the high content of montmorillonite (Al2 [Si4O10] (OH) 2 • nH2O) in clay, the gel additive has a framework structure characteristic for aluminosilicates. The presence of this additive in the composition strengthens the paintwork.
