ONE-COMPONENT, DUAL-CURE CONFORMAL COATING COMPOSITIONS |
| 摘要 |
Disclosed are one-component compositions that include: (1) an isocyanate-functional urethane acrylate and (2) a polyisocyanate containing allophanate and/or uretdione groups, wherein the one-component composition has a viscosity of less than or equal to about 500 mPas and an isocyanate content of greater than about 5% by weight, based on the weight of the one-component composition. Also disclosed are circuit boards and electronic components that are coated with such compositions. |

1. A one-component composition comprising:
1) an isocyanate functional urethane (meth)acrylate and 2) a polyisocyanate containing allophanate and/or uretdione groups,wherein the one-component composition has:
(i) a viscosity of less than or equal to about 500 mPas according to ASTM Standard D 7395-07 using a Brookfield R/S Rheometer at 25° C., 100 s-1 shear rate for 2 minutes with a C-50-1 spindle, and (ii) an isocyanate content of greater than about 5% by weight, based on the weight of the one-component composition. |
