Generally, the toxicity of amino terminated polyether in oral cavity or in contact with skin, eyes and mucous membrane can be ignored, so there is no need for personal protective measures in use. But because its alkalinity can irritate skin and eyes, it is necessary to wear safety glasses, gloves and other protective articles during operation.

Polyether amine technology is mainly through a series of technologies to produce the products we need, so what are the characteristics of the products produced? Next, I will give you a brief introduction. I hope you can deepen your understanding of polyether amine in the following introduction.

(1) fast curing, good adhesion to all kinds of substrates.

(2) polyether amine technology does not contain solvents and fillers, meeting the environmental requirements.

(3) it has excellent physical and chemical properties and wide adjustable range of physical and chemical indexes.

(4) good resistance to chemicals, anti-aging, and can be used in bad conditions for a long time.

(5) polyether amine technology adopts unique water removal technology to solve the influence of water content on the field spraying construction.

Before the sealant is purchased, the compatibility test and performance test between the sealant and the contact material must be carried out carefully. If there is no such report, the Contractor shall be urged to immediately entrust a testing agency with such qualification to carry out special test, and the qualified test can only be used.

Light color, color, transparent sealant has poor UV resistance, which is only suitable for indoor engineering; generally, black sealant should be used outdoors. The environment for storing glue shall meet the requirements of temperature and humidity to ensure a longer service life of sealing.

Waterproof sealant has a high advantage in the sealing of building materials such as doors and windows. It should also be prepared before use. The bonding sealing surface should be compact, solid, dry and clean without moisture, oil, dust, etc. Cut the sharp mouth to meet the requirements, and use a sharp tool to poke open the inner sealing aluminum film of the rubber outlet. Install the glue gun, and squeeze the glue into the place to be sealed. When the surface needs to be scraped flat, it shall be troweled with bamboo slices dipped in soapy water before the surface is dry.

After the preparation, the use quality of the waterproof sealant can be improved, the waterproof performance can be improved, and the good waterproof system of the building can be guaranteed.
