Generally found in the lowland and hill dipterocarp forests, swamp forests and schima-bamboo secondary forests. Heartwood Color Reddish brown Purplish Deposits in vessels may appear as white lines on the surface Darkens with age Sapwood Color Paler than heartwood Not clearly differentiated from the heartwood Grain Interlocked Even Twisted Seldom straight, possibly interlocked Interlocked Quartersawn surfaces may yield an attractive silver figure Texture Medium Medium coarse to coarse Even textured Luster Low Natural Durability Very little natural resistance Sapwood susceptible to attack by powder post beetles Odor No specific smell or taste Kiln Schedules T3 - C2 (4/4) US/T3 - C2 (4/4) U Drying Defects Splitting Quartersawn material less prone to degrade Material may warp and end-check during seasoning Ease of Drying Specific information on drying difficulty is not available Quartersawn material dries with little degrade Radial - 2.2% Shrinkage for Dillenia spp. (Green to Air-dry): Tangential - 3.9% Tree Size Bole length is 0-10 m Stilt roots are often present Product Sources Various species in the Dillenia genus from the Philippines are so similar to one another that they are often mixed and marketed together without any distinction. The most common ones are Katmon-bayani (D. megalantha), Malakatmon (D. luzoniensis), Katmon (D. philippinensis), and Katmon-kalabau (D. reifferscheidia). Boring Easy Cutting Resistance Easy to saw Sawn timber may spring immediately after sawing Fine dust may clog saw teeth Fairly easy to saw Nailing Nails hold poorly Planing Planing yields smooth surfaces Resistance to Impregnation Heartwood is somewhat permeable The heartwood response to preservative treatment is fair. Absorptions of 6 to 10 pcf of preservative oil have been reported Response to Hand Tools Easy to Work Turning Good results Numerical Data Item Green Dry English Bending Strength 6747 14355 psi Density 44 lbs/ft3 Hardness 1225 lbs Maximum Crushing Strength 3742 6350 psi Stiffness 1201 1676 1000 psi Specific Gravity 0.55 Weight 43 35. lbs/ft3 Item Green Dry Metric Bending Strength 474 1009 kg/cm2 Density 705 kg/m3 Hardness 555 kg Maximum Crushing Strength 263 446 kg/cm2 Stiffness 84 117 1000 kg/cm2 Specific Gravity 0.55 References Chudnoff, M.,1984,Tropical Timbers of the World,U.S.A.
