Report on the testing of

CT1 Power Grab ‘n’ Bond

4ward Testing Ltd were contacted by C-Tec N.I. Ltd of Unit 6, Ashtree Enterprise Park,Newry, County Down, Northern Ireland, BT34 1BY and asked to carry out a series of testson CT1 Power Grab ‘n’ Bond

Identification

Material: Construction AdhesiveCustomer Identification: CT1 Power Grab ‘n’ BondBatch No: 5790499Customer Reference: Marty McAlenan4ward Sample No: 3333Job No: 2656Date Received: 01/07/2015

Test Data

The Construction Adhesive was tested as received from the customer with samples beingprepared by the Laboratory.

The following tests were carried out using CT1 Power Grab ‘n’ Bond

Vertical butt pull-off test

The Construction Adhesive was used to adhere a steel dollie to a concrete substrate.Following cure time the dollie was removed from the concrete substrate which was held ina vertical position.

No of dollies: 3Diameter of dollie: 50mmCure time: 7 days @ 23±2°C, 50±5%RHTest machine: Instron 4204, UKAS calibration certificate:E105060515100830Speed of test: 5mm/min
