Types of Pens and Paints we stock
Pens and markers Pen manufacturers have followed Ladislao Biro's lead in producing new pens. A variety of pens make different ink marks -fine or broad, permanent or temporary - and will mark different surfaces including metal, glass and plastic. With the exception of the ball-point, fine tubes in the pens' nibs carry the ink by capillary action to the tip.
- Felt tip - The nib is made from natural or synthetic wool.
- Fibre tip - Resin-bonded fibres last longer than a felt tip.
- Ball-point - The ink is drawn to the nib by the action of the rolling ball.
- Plastic tip - Free flowing ink is fed through a hard-wearing plastic tip.
THE PROCESS THAT MAKES SUPERGLUE STICK
Superglue contains acidic stabiliser (red), which stops the adhesive molecules from linking and keeps the glue liquefied. The acidic stabiliser is neutralised on coming into contact with moisture (blue) on the surface which is to be bonded. Once the stabiliser has been neutralised, the adhesive molecules join together in long chains, forming a solid fixative.
