Adsorption promoter for photosensitive weld retarding agent
This adherence promoter of photosensitive welding retarder is obtained through the following reaction: where IV is pentaerythrite tri-acrylate or pentaerythrite trimethyl-acrylate; V is phosphorus pentoxide, phosphoric acid or phosphorus oxychloride; m=1 or 2; n=2 or 1; m+n=3; and R=H or -CH3.

Summary: | This adherence promoter of photosensitive welding retarder is obtained through the following reaction: where IV is pentaerythrite tri-acrylate or pentaerythrite trimethyl-acrylate; V is phosphorus pentoxide, phosphoric acid or phosphorus oxychloride; m=1 or 2; n=2 or 1; m+n=3; and R=H or -CH3. This promoter can be quickly solidified in the process of photo-setting, furthermore, it can raise the thermal resistance property of welding retarding film so that the welding film would not fall off under the impact of high temp. in the process of welding. |
