Description

LD8 Solvent-based developer

LD8 is a suspension of an inert white powder in a quick drying solvent. It is used e.g. in non-destructive testing of forged parts, welds, casts and drop forged parts. The LD8 developer is normally used with other Chemetall products such as the visible penetrant Checkmor 240 and the cleaner S76.

Density	0.96g/ml @ 20°C
Flash Point	-18°C

Instructions for use

Pre-cleaning, penetrant & excess penetrant removal

Clean part with S76 (or equivalent) before applying the penetrant. Apply cleaner to the part and wipe clean with cloth. Surface has to be free of grease, oil and dirt. Allow part to dry before applying penetrant. Apply a thin even film of penetrant to cover test area and allow penetration to cover test area and allow penetration as per the required time.

Remove excess surface penetrant with clean cloths, pre-moistened with cleaner. Alternatively removal can be affected by gentle water spray or by rinsing with water (for applications over 5°C). Do not flush surface with cleaner as sensitivity will be impaired. Repeat procedure until surface penetration has been removed. Thoroughly dry the component surface before developer application.

Developing 

LD8 are solid suspensions of solid particles which settle-out on standing; and therefore, aerosols and bulk containers must be shaken thoroughly before and during use.

Spray thin, even developer film over are to be inspected (spraying distance 30cm) surface temperature should be between -10°C and 50°C. LD8 must be applied by a light even spray (immersion or brushing will cause a loss of process sensitivity). When LD8 is used as part of a fluorescent penetrant process, it should be applied by successive spraying until a translucent layer is achieved.

Allow 10-30 minutes developing time before evaluation.
