Heat reaction / heat-curing repair putty Belzona 1251 HA Metal
For repairs of wall thinning in high-temperature piping and high-temperature equipment. A heat-curing type metal repair material that can be used for repairs without stopping even in emergencies.
[Overview] This is a one-component paste-like repair material that cures under high heat, specially formulated with a silicon alloy based on thermosetting resin. After curing, it maintains high durability and exhibits excellent corrosion resistance. It cures in 15 minutes at an operating temperature of 100°C, and can be used with simple surface preparation, allowing for use without stopping the operation of the equipment. *This product is not a hazardous substance. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ [Demo/Sample Distribution] If you wish to request a demo or sample, please fill out the application with your intended use and conditions in the "Contact Us" section below. *Please note that we may decline requests based on certain conditions. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
basic information
□Surface Preparation: Remove rust from the corroded areas of the metal using blasting, grinding, etc., and roughen the surface. *While simple surface preparation is possible for adhesion, more thorough preparation is necessary to enhance adhesive strength as much as possible. □Degreasing and Cleaning: Remove moisture, oil, dirt, etc., using a cleaning agent. □Application: Since it is a one-component heat-curing resin, no mixing is required. First, apply it by rubbing onto the prepared surface, then perform a second coat. However, at high temperatures, the material tends to sag, so a thickness of up to 6mm on horizontal surfaces and 3mm on vertical surfaces is recommended. □Curing and Aging: To ensure sufficient curing, a substrate temperature of 70 to 150°C is required, but curing time varies with temperature. Additionally, if the operating temperature is below 70°C, post-curing (forced heating) is necessary. For details, please refer to the instruction manual or contact us.
