Peter Young and His Background in Casting Impregnation
Peter was always right at the forefront of technology and responsible for developing and introducing polyester impregnation resin to the European market. This was followed by the very first methacrylate sealant patented and introduced in 1977 and followed up 10 years later with a methacrylate recycling sealant. In addition, Peter also has his name on a number of patents covering sealant formulation, process application and plant design.
He has also been an innovator in other fields of engineering. For example, he created the forerunner of todays condensing boilers. It was featured on Tomorrows World in the 1970s.
Peter David Young, the founder and owner of Ultraseal International Limited (1967-1998), spent his entire life in the impregnation business, being introduced to it by his father in 1949. See the history page for more details.
Ultraseal Polyester Sealant
In the mid sixties, Peter Young's father retired and sold his casting impregnation company. Peter took the decision to start his own company and formed Ultraseal in Slough in 1967. By this time, and as a result of on-going development, polyester sealant was being cured in hot glycol which was found to be the quickest and most effective curing method. The drawbacks with this type of sealant were that it produced an effluent that was difficult to dispose of and that it emitted an odour that required good ventilation.
Hot Cure Methacrylate Sealant
In 1977, Peter developed, introduced and patented the first hot water cure methacrylate sealant – PC504. This was a major breakthrough for Ultraseal and projected the company into the international market as a major player for the supply of sealants and equipment. The benefits were vast, predominantly drastically cutting effluent, speeding up process times by up to sixfold and a sealability that brought the application down from two to one treatment. Plant was also simpler and considerably more user friendly.
MX2 Recyclable Sealant
By the late 1980's Peter had a further breakthrough with the introduction of the first re-cyclable sealant – MX2. Not only was it special in this regard but it also exhibited greater application, flexibility and sealability than earlier impregnants.
MX became a mainstay of Ultraseal allowing it to develop a range of equipment to complement this unique sealant. Bearing in mind that over 95% of traditional sealant consumed during established processing was discharged down the drain – a total loss of a valuable chemical. This advanced green technology allowed the company to offer the market place a high performance system that could be applied in both its traditional top-load and front-load equipment.
Plant and Equipment
Both PC504 and MX sealants became the mainstays of Ultraseal, allowing it to develop a range of equipment to complement these unique sealants. Notably:
- 1980 – Balanced Dry Vacuum Impregnation
- 1983 – Fully Automatic In-Line Rotational Processing
- 1985 – Top Load Rotational Processing
- 1986 – Vertical Transfer Impregnation
- 1987 – Shuttle – fully automatic in-line impregnation system – British Design Council Award ‘Production Engineers’.
- 1988 – Front Load Rotational Processing
An MX Sealant impregnation plant manufactured by Ultraseal for Volvo Sweden in 1995, considered the largest of its kind, was a 5' diameter front load three-station system, comprising of vacuum impregnation, cold wash and hot water cure. In total, the machine was two stories high and weighed approx 15 tonnes dry. The cycle time was 2.5 mins per station. Each batch contained eight aluminum cylinder blocks.
In 1979/80 a number of international patents were granted, covering original PC504 and the method of impregnation sighting the novelty of hot water curing. There followed a series of additional patents both for new sealant formulations and process application spanning some twenty years.
These are a selection of Peter D. Young's patents. Unfotunately the links often go out of date, when the destination websites are rearranged. We can only apologise if this is the case.
