Gel Coat Resin
gel coat resin for chimneys and water towers REL-8318

Description:

REL-8318 Unsaturated Polyester Resin is a gel coat resin specifically developed for the long-term protection of outdoor concrete or steel structures such as chimneys and water towers. Its balanced medium reactivity ensures controllable application, while its excellent water resistance, crack resistance, and impact resistance form a tough, dense protective layer. This effectively prevents moisture penetration, withstands thermal stress and environmental erosion, and significantly extends the service life of the substrate.


Performance Attributes:

Medium reactivity. Good crack resistance, good impact resistance and good water resistance


Type:

ISO

Storage:
Stored at temperatures below 25ºC. Storage life decreases with increasing storage temperature. Avoid exposure to heat such as direct sunlight or steam pipes. To avoid contamination of the product with water, do not store outdoors. Keep sealed to prevent moisture pick-up and monomer loss. Mild mixing is recommended after prolonged storage. Rotate stock.

Features & Applications

Features:REL-8318 Unsaturated Polyester Resin is a water-resistant and crack-resistant gel coat resin designed for protecting chimneys and water towers. It offers good impact resistance and water resistance, and its medium reactivity ensures balanced curing speed and ease of application.8.jpg
Applications:

Protective Coating for Chimney Interiors: Used on the inner walls of chimneys, its good crack resistance and water resistance effectively protect against erosion and cracking caused by high-temperature flue gas condensates and temperature fluctuations.

Water Tower/Storage Tank Linings: As a lining coating for water towers or storage tanks, its excellent water resistance and crack resistance provide long-term prevention of water leakage and resistance to internal water pressure changes.

Protection for Concrete Structures such as Cooling Towers: Suitable for outdoor concrete structure surfaces like cooling towers, it provides a weather-resistant and waterproof protective layer, enhancing structural durability and resisting environmental erosion.
