Two-Part Epoxy Glue: Bis-Phenol Resin Thinned with Allyl Glycidyl Ether, Hardened with Diethylene Triamine

Bis-phenol epoxy resin is too thick to spread, so it is thinned with a fifth of its weight of allyl glycidyl ether, which joins the cure. That is part A; part B is diethylene triamine. Stir 10 parts of B into 100 of A, spread, join, and it hardens at room temperature: after six days at 25 °C, block joints held 3,550 lb/in² (Wiles and Newey, Shell, US 2,528,932, 1950). It bonds wood, metal and resins. The picture: our drawing of the two bottles and a glued joint.

A week to full strength

안내

Make part A

Warm 400 g bis-phenol epoxy resin until it flows (our step; it softens at 43 °C) and stir in 100 g allyl glycidyl ether, to a smooth, spreadable syrup. Bottle it.

이 단계의 재료:

비스페놀 에폭시 수지400 g

알릴 글리시딜 에터100 g

필요한 도구:

붕규산 비커

전열판(핫플레이트)

젓는 도구

온도계

디지털 주방 저울

뚜껑 달린 유리병

고무장갑

Bottle part B

Bottle diethylene triamine separately and keep it closed: it is strongly alkaline and burns skin. You need 10 g for every 100 g of part A.

이 단계의 재료:

다이에틸렌트라이아민50 g

필요한 도구:

뚜껑 달린 유리병

고무장갑

Mix only what you need

Weigh part A into a cup, add a tenth of its weight of part B, and stir well. It begins to cure at once, so mix just before gluing.

Spread, join, wait

Spread a thin coat on both faces and press them together. At room temperature it sets in half an hour to a day and reaches full strength in one to two weeks; warmth speeds it up.
