Simple Art of Gluing Timber

0 Comments| Posted in Technical Reports By Adhesive Consultant
Preparation and Machining – Careful attention to the machining and preparation of edges before assembling will result in obtaining the strongest possible bonds. Planning the edges to be bonded is recommended over against using a circular saw, as saw blades tend to damage the bonding surfaces by tearing the wood fibres as they cut, leaving a rough surface which often requires excessive clamping pressure to bring the two surfaces together; where as a planner shears the fibres longitudinally, leaving them undamaged, with a flat surface, that requires less clamping pressure, leaving an almost invisible glue line.

Sealant Technologies

0 Comments| Posted in Technical Reports By george petraru
The main difference between adhesives and sealants is that sealants typically have lower strength and higher elongation than do adhesives. Since the main objective of a sealant is to seal assemblies and joints, sealants need to have sufficient adhesion to the substrates and resistance to environmental conditions to remain bonded over the required life of the assembly.

Contact Cement is an Adhesive, which, when coated on two mating surfaces and allowed to dry, provides an instant permanent bond when pressure is applied. Pressure is one of the most important ingredients or steps in the procedure to getting a quality bond. You need a minimum of 20”per sq foot to achieve this.

The development of new materials with diverse applications puts additional challenges on processing technology. This is particularly so when different materials have to be joined to make components which retain their individual beneficial properties in the composite product.

Adhesive Bonding

0 Comments| Posted in Technical Reports By george petraru
Adhesive bonding is used to fasten two surfaces together, usually producing a smooth bond.  This joining technique involves glues, epoxies, or various plastic agents that bond by evaporation of a solvent or by curing a bonding agent with heat, pressure, or time.  Historically, glues have produced relatively weak bonds.
