Conventional Sealant

Ultraseal PC504/66

The highly approved PC504/66 methacrylate sealant has over recent decades become the benchmark for sealing performance and quality in a wide variety of applications, offering unrivalled performance and temperature stability alongside consistently high productivity.
As well as providing greater productivity, this pioneering sealant was the first to offer consistently high quality, whilst also avoiding the safety and environmental issues associated with its predecessors.

These factors saw Ultraseal PC504/66 rapidly become the preferred choice worldwide in sectors ranging from military and aerospace components to high volume automotive applications. With a proven track record spanning more than a quarter of a century in these demanding applications, it offers unrivalled quality in terms of sealing performance and temperature stability.

Exhaustive trials in Europe, the USA and Japan – the world’s most technically demanding markets – show it can operate effectively between -50°C and 200°C, in metal castings, plastic mouldings, sintered components other porous materials.

Ultraseal PC504/66 also offers low shrinkage during polymerisation, producing an outstanding void filling capacity, while the product’s low viscosity enables faster, deeper penetration even into the finest micro-porosity.

It is suitable for use in both large batch and lean manufacturing applications, producing consistent high quality performance, whatever the size or nature of the components being treated.

This approval process subjects test rings to a number of stringent sealing capability tests. These show the chemical resistance and thermal stability over a wide range.

Ultraseal EC505

Ultraseal is always striving to develop new products to bring tangible advantages to its customers whilst taking due regard of the environment and the ever changing Health & Safety legislation. Most methacrylate sealants have some elements which are dangerous to the environment and are toxic to aquatic organisms requiring them to be labelled with “dead fish dead tree” symbols.

Ultraseal EC505 sealant has recently been developed and is specially formulated to have low eco-toxicity by careful selection of raw materials and is not classified as toxic to aquatic organisms. The formulation has also focused on good washability to minimise or eliminate polymer build up on baskets.

In keeping with all of the Ultraseal range EC505 sealant exhibits low consumption rates and excellent sealabilty together with high temperature and chemical resistance.
