Abstract

Det er beskrevet et kolloidalt aggregat egnet til anvendelse ved herdningen av harpikser omfattende en kontinuert fase av et vannbasert innkapslingsmateriale og en dispergert fase omfattende en eller flere sterke syrer. Den kontinuerte fasen omfatter fortrinnsvis en blanding av gelatin og xantangummi. Aggregatet lydbehandles for å innkapsle syren i innkapslingsmaterialet. Den innkapslede syren blandes med en herdbar harpiks. Syrekapslene kan brytes på en hvilken som helst egnet måte, men fortrinnsvis ultralyd, for å frigi syren og initiere herdningen av harpiksen.There is disclosed a colloidal assembly suitable for use in the curing of resins comprising a continuous phase of a water-based encapsulating material and a dispersed phase comprising one or more strong acids. The continuous phase preferably comprises a mixture of gelatin and xanthan gum. The unit is audio processed to encapsulate the acid in the encapsulating material. The encapsulated acid is mixed with a curable resin. The acid capsules may be broken in any suitable manner, but preferably ultrasound, to release the acid and initiate the curing of the resin.
