| These formats allow the choice between time, to assemble more complicated or larger pieces of work and speed, to finish a job on the same day. Rapid, Regular and Gel have the same strength. All can be used in very cold temperatures and up to whatever our summers can throw at us. The recommended working minimum is +5°C with 80% humidity. | |

strength of a glued joint is achieved by well-fitting, well-clamped surfaces
brought together within the open joint time. It is worth remembering that
the surface area glued also plays a large part in the strength of a glued
joint. For instance, the length of a scarf, the length of a tenon etc.
We are often asked: "How can Balcotan 100 be a one component glue and yet be 100% waterproof?" The answer is simple. Balcotan 100 is not soluble in water, either before or after curing. It uses the humidity in the air and the moisture in the material being glued to activate the curing process without diluting the glue or damaging the adhesive properties. |

| Safety in the Working Environment | |
|
As curing does not take place by evaporation or absorption, no solvents
are necessary in the adhesive. In addition it is not a fire hazard
so the work space is safer. Polyurethane's may cause breathing difficulties when vapourised in the air. However the vapour pressure of Balcotan 100 is so low that in use it releases no dangerous vapours into the work place. |
|
| Other Characteristics of Balcotan | |
| Like
all liquid Polyurethane adhesives, Balcotan 100 foams as it cures.
However it is uniquely formulated to control the amount of foaming
during cure, which protects the joint from undue pressure. The controlled foaming action means that: 1. Glue only need be applied to one face. The expanding action will wet the other surface when the two are brought together. 2. Crevices in the wood, the bottom of splines and tenons and small spaces between glued faces are automatically filled without having to unduly "load up" a loose joint. This is particularly useful where say, the joints of a piece of furniture are being re-glued after it has been stripped in a caustic bath. Or where multi-laminate (cold-moulded) hulls are glued up, the foaming property inhibits voids being left between the layers, and the consequent overall adhesion ensures structural integrity. When laminating veneers, it is recommended that their thickness should be 1 .6mm minimum for staple fastened lay-up at 45mm centres. 3. Because the expanded adhesive is a foam, and not a resin like epoxy, it is not recommended for use as a structural filler. |
